Abstract

A plug-and-play (PnP) interconnection architecture and method with an in-device storage module in a peripheral device are proposed for interconnecting a peripheral device with a host computer unit. The proposed architecture is characterized by integration of an in-device storage unit with internal functional modules of the peripheral device for storing device specific data and software such as the dedicated device driver of the peripheral device. An enhanced plug-and-play (ePnP) layered structure is proposed based on the in-device storage architecture. The ePnP provides a mechanism to PnP peripheral devices' functions customization. An application of the ePnP is the mechanism to bring up the device driver automatically when the peripheral device is connected to the host computer unit. This auto-installation mechanism provides a truly plug-and-play capability to the user.

Description

200411394 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a computer peripheral device technology. More specifically, it relates to a plug-and-play method for a storage module built into a peripheral device ( plug-and-play (PnP) connection architecture and method for providing users without having to install a peripheral device-related software (including a driver) to connect the peripheral device to a host computer for use. [Previous technology] Plug and play is a peripheral device connection technology used to provide users with a peripheral device such as a monitor, modem, printer, keyboard, mouse, and external storage device, and a personal computer, Host computers such as workstations or servers are connected to each other without manually setting the internals of the computer, such as including interrupt request (IRQ), direct memory access (DMA), input, output, and memory addresses Wait for the basic input / output system setting value. As mentioned earlier, the user can use the peripheral device by plugging it into a personal computer without manually setting the basic input / output system settings of the personal computer. Therefore, even if the user is not familiar with the basic input / output system settings of the computer, he / she must successfully install a new peripheral device on his or her brain. However, the known plug-and-play connection architecture still has some inconveniences. The user must still manually install the driver of the peripheral device in the host computer, which is not only time-consuming but also inconsistent with the so-called "plug and play" name, which is one of them. Because these device drivers and related product information are usually stored on a magnetic disk, read-only disc, or digital image disc, for the manufacturer, more labor and cost must be invested to manufacture the product, resulting in the computer week.

In order for the host computer to recognize the plug-and-play peripheral device, the setting data corresponding to the plug-and-play peripheral device must be stored centrally in the host computer. The host computer was required to maintain a large database of plug-and-play peripheral devices, which further caused the bottleneck of plug-and-play peripheral device applications. [Summary of the Invention] The main object of the present invention is to provide a plug-and-play connection architecture and method for storing a storage module in a peripheral device, and the peripheral device can be easily accessed by a host system or a host computer.

Therefore, the host computer 10 re-detects that the side device is plugged in, and enters the initialization process as shown in FIG. 3. After the state S40 is completed and completed, the peripheral device 20 returns to the state S20, which is the ready state and waits for the next signal from the host computer 10. In state S20, when the peripheral device 20 receives a signal from the device transmitted by the host computer 10, it immediately proceeds to state S50. The flag of the peripheral device 20 will be set to "1", and if the counter is determined, It is also "1", and the plug-and-play connection between the peripheral device 20 and the host computer 10 is sequentially released and established.
